I'm no expert but 1.6mm seems a little optimistic for a floorpan? My Ally floor on the Locost is 2mm.
Someone with more knowledge than my humble self will be along soon I'm sure

I would have said 2mm as minimum thickness.

Hi Austen.
Only ever used NS4. 1.2 mm. Just make sure you have a cross member just in front of your backside to reduce any flex in that area. Assuming that you
are bonding and riveting to a decent standard.

1.2mm was ideal on my Westfield (430Kg Megabike), supplied by the factory at the time. My Sylva-derived car has 1.6mm, feels very thick and heavy by
comparison. Thing is, the Westfield has two 2" steel strips across the floorpan on which the seat sits, the Sylva-derived thing doesn't,
the seat bases go straight on the alloy. Rivet spacing is very generous on the Westfield, very tight on the Sylva-thingy.
2mm sounds great for rallying....

We use 2mm t6 but that's to add stiffness.
Also means that no kerbs or bumps will damage it and should last almost forever

mmmmmm

I know I like overkill sometimes but my 1.6mm steel floor certainly stopped something hard coming through. what ever it was left about a 10mm dent in
the underside of the trans tunnel.
It's down to what roads you use and if lots of track days, I guess.
If you need to end up bracing with steel will you save that much weight?

The sylva riot is 1.2mm NS4. I plan to use 1.5 because its felt a lot less flexible and was only a few of quid extra.

Not sure on the thickness, but i'm planning on using an old pub sign as my floor - which I think is at least 2mm alu. My seat runners are going
to be mounted on 25mmx3mm strips running width ways across the car. I'm not too bothered about the extra weight, more interested in having some
serious @rse protection in place :-D

I tend to do the opposite - I use the pub floor as a sign [that I've had too much beer].
I'll get my coat.

Btw for anyone who actually wants to buy this material in the year 2013, it's now and has been for sometime called 5251.

When i last looked into this, i thought we were looking at 3mm Ali, 2mm steel min?
Or is that really overkill?

Yes that's extreme overkill on the steel even for a road car, a tin-top will have 1mm steel floor but shaped so you don't get the
"boing" effect.
When using NS4 / 5251 you certainly don't need more than 2mm unless you plan on driving over bricks on a regular basis.
For a racer enough to keep your bum off the road and water out is as much as you need.

I used 1.5mm thick 5251 for racing, next time I'll drop to 1.2mm 5251 though.
